установить сопоставление uid пространства имен пользователя (set the uid mapping of a user namespace)
Имя (Name)
newuidmap - set the uid mapping of a user namespace
Синопсис (Synopsis)
newuidmap pid uid loweruid count [uid loweruid count [ ... ]]
Описание (Description)
The newuidmap sets /proc/[pid]/uid_map based on its command line
arguments and the uids allowed. Subuid delegation can either be
managed via /etc/subuid or through the configured NSS subid
module. These options are mutually exclusive.
Note that the root user is not exempted from the requirement for
a valid /etc/subuid entry.
After the pid argument, newuidmap expects sets of 3 integers:
uid
Beginning of the range of UIDs inside the user namespace.
loweruid
Beginning of the range of UIDs outside the user namespace.
count
Length of the ranges (both inside and outside the user
namespace).
newuidmap verifies that the caller is the owner of the process
indicated by pid and that for each of the above sets, each of the
UIDs in the range [loweruid, loweruid+count) is allowed to the
caller according to /etc/subuid before setting
/proc/[pid]/uid_map.
Note that newuidmap may be used only once for a given process.
